Aligning the machine to the driven machine and mounting

5.5.2.1

Horizontal types of construction with mounting feet

1. Refer to any instructions for aligning the driven machine and those of the coupling
manufacturer.
2. Align the machines with coupling output to the driven machine in such a manner that the
center lines of the shafts are parallel with no offset. This ensures that no additional forces
affect their bearings during operation.
3. For the vertical positioning (x→0) place thin shims under the machine feet. The number of
shims should be kept as low as possible, i.e. stack as few as possible. This also prevents the
machine being subjected to any stress/distortion. If available, use the existing tapped holes
for the forcing-off bolts to somewhat raise the machine.
4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
the coupling.
5. Fix the machine to the foundation. The choice of fixing elements depends on the foundation
and is the plant operator's responsibility.
Note
Machine expansion
When aligning, make allowance for the thermal expansion of the machine when the
temperature increases.

5.5.2.2

Horizontal types of construction with flange

The standard flange is provided with a centering. The choice of fit for the mating flange on
the driven machine is the system manufacturer's or the plant operator's responsibility.
If the machine is not fitted with a standard flange, align the machine to suit the driven
machine.
